Research published in BioMed Central's open access journal, Genome Medicine, outlines an innovative clinical diagnostic test for the early identification of a wide range of mitochondrial disorders. Mutations to one of the mitochondrial genes, or to a number of nuclear genes with roles in mitochondrial function, can cause diseases which have very similar symptoms, making them difficult to diagnose and treat. http://www.physorg.com/news175458133.html Medicine & Health Thu, 22 Oct 2009 20:30:09 EST news175458133 After 15 years of research in the waters of the South Atlantic and Indian Oceans, scientists from the Wildlife Conservation Society, the American Museum of Natural History, and an international coalition of organizations have unveiled the largest genetic study of humpback whale populations ever conducted in the Southern Hemisphere. http://www.physorg.com/news174718568.html Biology Wed, 14 Oct 2009 06:10:01 EST news174718568 Scientists look for clues about therapies and cures for life-threatening childhood illnesses in children's DNA -- it seems only logical to do so. But the decision as to who should have access to DNA samples from children provides a unique ethical conundrum, says a Tel Aviv University researcher in a recent publication for the esteemed journal Science, co-authored by colleagues from The Netherlands and Canada. The recommendations, which call for new policies on access to biobanked children's DNA, could shape America's legislation on the issue in the coming years. http://www.physorg.com/news174052464.html Medicine & Health Tue, 06 Oct 2009 13:40:07 EST news174052464 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists have discovered why Holsteins -bred to produce more milk -are less fertile than before breeding efforts were stepped up to increase dairy production: It's in their DNA. http://www.physorg.com/news173955686.html Biology Mon, 05 Oct 2009 10:30:01 EST news173955686 (PhysOrg.com) -- Depending on your genes, Salmonella can mean a lot more than food poisoning. In a new clinical study, researchers at The Rockefeller University Hospital are narrowing in on the genetic link that predisposes a person to a set of complications known as severe nontyphoidal salmonellosis (SNTS). The study will analyze medical records and blood samples of SNTS-diagnosed children and may clarify the role of genetics in the immune system`s various responses to Salmonella infection and lead to more efficient treatments for the disease. http://www.physorg.com/news173635029.html Medicine & Health Thu, 01 Oct 2009 16:58:38 EST news173635029 (PhysOrg.com) -- One of the enduring mysteries of lung cancer is why so many people who never smoked develop the disease.
